Inmarsat has marked the 25th anniversary of Inmarsat C by revealing that more than 600 distress alerts from vessels in urgent need were broadcast over the service in 2015.

The disclosure demonstrates how the decision made by IMO administrations requiring all ships of more than 300 gross tons to be fitted with a Global Maritime Distress and Safety System (GMDSS) remains pivotal in protecting lives at sea.

The Inmarsat C service provides a critical link between vessels in distress and Maritime Rescue Coordination Centres (MRCCs) around the world. With proven availability of 99.9%, Inmarsat C always prioritises seafarer distress alerts to MRCCs and to nearby ships. Today, approximately 100,000 vessels rely on Inmarsat C to provide vital communications, at the press of a button.
